We are ready to start executing a new 6-task plan on the main development branch. What environment isolation step must be completed before any subagent starts writing code?
| Checked | Without skill | With skill |
|---|---|---|
| Requires creating a git worktree workspace before starting implementation | Missed | Passed |
The instructions your model reads when the skill loads.
Execute plan by dispatching fresh subagent per task, with two-stage review after each: spec compliance review first, then code quality review.
Core principle: Fresh subagent per task + two-stage review (spec then quality) = high quality, fast iteration
